In October 2014, Seattle launched Pronto, a docked bike-share program. But Pronto had problems shifting into a higher gear, and the city ended the program in 2017, making Seattle one of the few cities in the world to shut down a modern public bike sharing system. (more…)
Like humans, some song sparrows are more effusive than others, at least when it comes to defending their territories. New findings from the University of Washington show that consistent individual differences exist not only for how aggressive individual song sparrows are but also for how much they use their signals to communicate their aggressive intentions.
The findings, published online Dec. 4 in Proceedings of the Royal Society B, show that while many birds signal their intentions clearly, other “strong silent types” go immediately to aggressive behavior and ultimately attack without first signaling their intentions. (more…)
A model of great ape history during the past 15 million years has been fashioned through the study of genetic variation in a large panel of humans, chimpanzees, gorillas and orangutans. The catalog of great ape genetic diversity, the most comprehensive ever, elucidates the evolution and population histories of great apes from Africa and Indonesia. The resource will likely also aid in current and future conservation efforts which strive to preserve natural genetic diversity in populations.
More than 75 scientists and wildlife conservationists from around the world assisted the genetic analysis of 79 wild and captive-born great apes. They represent all six great ape species: chimpanzee, bonobo, Sumatran orangutan, Bornean orangutan, eastern gorilla, and western lowland gorilla, and seven subspecies. Nine human genomes were included in the sampling. (more…)
A new Star Trek app for Windows 8 and Windows Phone kicked off an unprecedented cross-company partnership to promote “Star Trek Into Darkness,” the new film from Paramount Pictures. Star Trek movie-themed content will materialize across Microsoft’s consumer products and services leading up the May 16 release of the highly anticipated new movie.
REDMOND, Wash. – May 15, 2013 – Star Trek and Microsoft — a logical pairing, Spock might say.
Paramount Pictures thought so. (more…)
As part of its YouthSpark initiative to create opportunities for youth, Microsoft welcomes 15,000 students to We Day at Seattle’s KeyArena.
SEATTLE — March 27, 2013 — At the age of 12, while looking for the morning comics in the newspaper, Craig Kielburger stumbled upon a news item about a 12-year-old boy killed in Pakistan for speaking out against child labor. Outraged by the story, he desperately wanted to do something to help. After a number of phone calls and attempts to contact nonprofit organizations, Kielburger realized it wasn’t so easy for kids to get involved with social activism. That’s when he got an idea.
That same year, the young Canadian founded his own nonprofit, Free The Children, to pave the way for kids to help other kids around the world. Twelve years later, in 2007, Kielburger took his organization to the next level, launching the We Act program in schools across Canada and creating a more widespread approach to helping youth make a difference. As part of the program, Free The Children hosts a celebration in each participating city called We Day. (more…)
Species facing widespread and rapid environmental changes can sometimes evolve quickly enough to dodge the extinction bullet. Populations of disease-causing bacteria evolve, for example, as doctors flood their “environment,” the human body, with antibiotics. Insects, animals and plants can make evolutionary adaptations in response to pesticides, heavy metals and overfishing.
Previous studies have shown that the more gradual the change, the better the chances for “evolutionary rescue” – the process of mutations occurring fast enough to allow a population to avoid extinction in changing environments. One obvious reason is that more individuals remain alive when change is gradual or moderate, meaning there are more opportunities for a winning mutation to emerge. (more…)
Territorial song sparrows use increasingly threatening signals to ward off trespassing rivals. First an early warning that matches the intruder’s song, then wing waving – a bird’s version of “flipping the bird” – as the dispute heats up, and finally, if all other signals have failed, attack.
This hierarchical warning scheme, discovered by researchers at the University of Washington, adds nuance to a communication system that has been long-used as a model to study how people use and learn language (more…)
On Mars, as on Earth, sometimes things can take on an unusual appearance. A case in point is a shiny-looking rock seen in a recent image from NASA’s Curiosity Mars rover.
Some casual observers might see a resemblance to a car door handle, hood ornament or some other type of metallic object. To Ronald Sletten of the University of Washington, Seattle, a collaborator on Curiosity’s science team, the object is an interesting study in how wind and the natural elements cause erosion and other effects on various types of rocks.
